Soulstone GFX

Ok so Im pretty sure everyone knows the +25con stones has a sparkle effect when you wear 4 of the same stone on one piece of armor. Ive been trying to dig around to editing the GFX for it or even just being able to replace the GFX on the 25con stones to the lightning effect that you get with lvl8+HP soulstones. There was sort of a topic about this while back :here: But it doesnt exactly explain where the pathway to the gfx is, I actually changed all the gfx's that were in the location of the ecm files, but still no go >.<
Actually when I had changed the GFX located in the ECM of the 25con stones, all it did was change the effect for when the item is dropped on the ground. So I am guessing there is another ecm or gfx for these 25con stones. Does anyone happen to know where the location is? <__<; Attached 2 images showing both effects that I am talking about >.<
